Description and Introduction

RESET CIRCUIT The STM812LW16F is a microprocessor supervisory circuit from STMicroelectronics. Here are the factual details from Ic-phoenix technical data files:  

### **Manufacturer:**  
STMicroelectronics  

### **Specifications:**  
- **Type:** Voltage Monitor / Supervisor  
- **Voltage Threshold:** Adjustable or fixed (specific threshold depends on variant)  
- **Output Type:** Active-low reset  
- **Operating Voltage Range:** Typically 1.0V to 5.5V (exact range may vary)  
- **Reset Timeout Period:** Adjustable or fixed (e.g., 140ms, 280ms, or other)  
- **Package:** SOT-23 or similar small form factor  

### **Descriptions:**  
- Monitors system voltage and generates a reset signal if voltage falls below a threshold.  
- Ensures proper microcontroller or processor initialization during power-up/down.  
- Low quiescent current for power-sensitive applications.  

### **Features:**  
- Precision voltage monitoring  
- Manual reset input (if applicable)  
- Low power consumption  
- Wide operating voltage range  
- Small footprint package  

For exact threshold values, package type, or other specifics, refer to the official STM812LW16F datasheet from STMicroelectronics.

Application Scenarios & Design Considerations

RESET CIRCUIT

Alternative Part Number

  • MAX811LEUS+T --: Pin-compatible microprocessor supervisor with 4.63V reset threshold and active-low push-pull reset, matching the STM812L function in a SOT-143 package.
  • TPS3808G33DBVR --: Adjustable-threshold supervisor with programmable reset delay and active-low open-drain output, suitable replacement for supply monitoring and reset generation.
  • MCP131T-450E/TO --: Low-power voltage supervisor with 4.5V trip point and active-low reset output, offering similar reset timing behavior in a small TO-92 package.
